How to Uninstall CloudLinux from cPanel

Uninstalling CloudLinux from a cPanel server can be a meticulous process, but with the right steps and attention to detail, it can be done effectively. CloudLinux is a popular operating system used to enhance server stability and security, but there may be situations where you need to revert to a standard CentOS distribution. This guide will walk you through the entire process, ensuring you have all the information needed for a smooth transition.

This blog is a part of our cPanel server management services where we make sure your cPanel server works efficiently with any issues.


Before beginning the uninstallation process, ensure you have the following:

  • Root access to your server.
  • A full backup of your server data.
  • Basic knowledge of using SSH and command-line interfaces.

Step-by-Step Uninstallation Process

Step 1: Prepare Your Server

Backup Your Data:

Ensure you have a complete backup of your server. This is crucial as the uninstallation process can lead to data loss if not handled properly.

tar -czf backup-$(date +%F).tar.gz /path/to/important/data

Check the Current Version:

Verify the current version of CloudLinux and cPanel installed on your server.

uname -r

rpm -qa | grep cloudlinux

Step 2: Remove CloudLinux Packages

Switch to CentOS Kernel:

First, you need to switch from the CloudLinux kernel to the CentOS kernel. List the available kernels:

rpm -qa | grep kernel

Install the CentOS kernel if not already installed:

yum install kernel

Set the default kernel to the CentOS kernel by editing the GRUB configuration file. Open /etc/grub.conf or /boot/grub/grub.conf in a text editor and set the default to the CentOS kernel.


Reboot the Server:

Reboot your server to boot into the CentOS kernel.


After the reboot, verify that the server is running the CentOS kernel:

uname -r

Remove CloudLinux RPM Packages:

Uninstall all CloudLinux packages:

yum remove liblve lve-utils lve-stats alt-python27-cllib cagefs lvemanager rhn-check rhn-client-tools rhnlib rhn-setup rhn-setup-gnome yum-rhn-plugin

Step 3: Convert Back to CentOS

Restore CentOS Repositories:

Replace the CloudLinux repositories with the original CentOS repositories. Remove the CloudLinux repository configuration files:

rm -f /etc/yum.repos.d/cloudlinux.repo

Restore the CentOS repository files. You may need to download the CentOS repository configuration package and install it:

yum install centos-release

Sync with CentOS Repositories:

Clean the YUM cache and sync the packages with the CentOS repositories:

yum clean all

yum update

Step 4: Final Cleanup

Reinstall Necessary Packages:

Reinstall any necessary packages that were removed during the process to ensure that cPanel functions correctly. For example:

yum install -y perl ruby

Verify the cPanel Installation:

Run the cPanel installation script to verify and repair the cPanel installation:

/scripts/upcp –force

Reboot the Server:

Finally, reboot the server to ensure all changes take effect:


Step 5: Post-Uninstallation Checks

Check Kernel Version:

After the final reboot, ensure the server is running the correct CentOS kernel:

uname -r

Verify cPanel Functionality:

Log in to the cPanel interface and verify that all services are running correctly. Check for any errors and resolve them as needed.

Monitor Server Performance:

Monitor the server for a few days to ensure stability and performance are as expected. Pay attention to server logs and performance metrics.


Uninstalling CloudLinux from cPanel is a process that requires careful execution to avoid disrupting server operations. By following the steps outlined above, you can successfully revert your server back to a standard CentOS distribution. Remember to take necessary precautions, such as backing up your data and verifying each step, to ensure a smooth transition.
